Historically, the biggest barrier to using ParaView for most beginners is getting their data into ParaView. While ParaView supports a wide variety of file formats, new formats are created all the time. Additionally, existing formats may become popular enough that they warrant the development of customized readers in order to load the data into ParaView. […]

This past month, ITK 4.5.0 was released! Below is the introduction, new documentation, and new features sections of the release notes. Introduction The 4.5 release is a major milestone that marks the hard work of many outstanding community members. Among the major contributions in this release are registrations computed with 32-bit floats, a new edition […]

We are pleased to announce the release of version 0.7.2 of the Avogadro 2 application and libraries. The new version’s source and binaries are available on our website or on SourceForge. The release features a few bug fixes after the recent 0.7.1 release, such as a Python interpreter path path fix, and some improvements with […]

matplotlib is a Python module that can be used to make publication-quality plots. We have recently integrated matplotlib into ParaView as a new type of view called a “Python View”. This new view will be available in the ParaView 4.1 release. Below is a screenshot of the new Python View (right) next to a 3D rendering […]

We are pleased to announce the release of version 0.7.0 of the Avogadro 2 application and libraries. The new version’s source and binaries are available on our website or on SourceForge. The release features a number of enhancements to the application and libraries including support for text rendering, a measurement tool, bond-centric manipulation of the […]

Congratulations to our collaborators at the University of Houston, Cullen College of Engineering. Dr. Nicholas Rey, a member of Dr. Badri Roysam’s lab at the University of Houston, is presenting their FARSIGHT toolkit at the European BioImage Analysis Symposium (EuBIAS), Barcelona, Oct 7-11. FARSIGHT is a popular toolkit for medical image analysis, particularly for neuronal […]

Index To the Series 1. Raspberery Pi likes Open Source 2. Cross-Compiling for Raspberry Pi 3. Cross-Compiling ITK for Raspberry Pi 4. Raspberry Pi likes VTK 5. Raspberry Pi likes Node.js   Following on our series exploring the use of the Raspberry Pi, Here we describe how to use Pi Camera.   First: The Hardware […]

VeloView 1.0 Released In September, Kitware and Velodyne LiDAR released VeloView 1.0, an open-source application designed for real-time, 3D visualization and analysis of point cloud data generated by Velodyne’s 3D LiDAR sensors HDL-32E and HDL-64E. The application provides an easy-to-use tool for visualization and processing of Velodyne’s data-rich, 3D LiDAR sensors, supporting live sensor streams […]

It is becoming increasingly difficult to efficiently leverage supercomputers for computational research. There are a variety of factors contributing to this: more concurrency, heterogeneous processing units, relative slow-down of memory bandwidth, and file IO to processing power, etc. This corresponds to a large increase in our ability to crunch numbers with a small increase in […]

Laparoscopic surgery is a minimally invasive surgical approach in which instruments are passed through ports placed at small incisions. Typically, a surgeon will use her own medical intuition and external landmarks on the patient to select the placement of the surgical ports through which to pass the surgical instruments. However, this port selection strategy can […]

Kitware and NYU-Poly have been working together on the development of open-source tools and libraries to make it easier for developers to provide sophisticated, interactive geoinformatics over the web. Kitware and NYU-Poly, along with help from climate scientists from National Labs and NASA, are collaborating on ClimatePipes [1] project, the goal of which is to […]

For effective software development, the edit-compile-test cycle should run quickly.  In order to get a better understanding of ITK‘s test times, we created a Python script that visualizes CTest test times with VTK‘s TreeMapView. ITK test times. Tests that run longer have a proportionally larger area.  With the visualization, it is clear that there are some tests […]

I’m excited to announce the release of VeloView 1.0!  VeloView is an open-source application designed for visualization and analysis of point cloud data generated by the Velodyne HDL lidar sensor.  VeloView is the result of a collaborative effort between Velodyne Lidar and Kitware, Inc. About the Velodyne HDL Sensor The HDL sensor is famous for […]

The Python Programmable Filter is a powerful tool for data analysis in ParaView, as it enables you to implement ParaView readers and filters using Python. Developing filters with Python has several advantages– it's fast to prototype and easy to share, since there's no compiled code. You can use the convenient features of the standard Python […]

ParaView 4.0.1 was released in mid-June, marking the first major change in version number since 2007. This release also marks a milestone in the gradual progression of the user interface and framework, and addresses more than 130 issues since the release of ParaView 3. ParaView 4.0.1 is based on VTK 6.0, and includes all related […]

In late June, the VTK community released VTK 6.0, the first major release since 5.0 in December 2005! This release includes significant refactoring of VTK’s pipeline and build system. Pipeline changes have cleanly separated the Algorithm, DataObject, and Executive classes. Build system changes automate and simplify intra-library build time dependency analysis. Together these changes facilitate […]

VTK 5.10.0 was tagged on May 12, 2012, with a bug fix release made on October 15. For many months, we worked on the modularization of VTK using a set of tools to automate the file moves and maintain a testing tree that was parallel to the current master. A lot of that work was […]

Motivation Observations unequivocally show that the global climate is changing, caused over the past 50 years primarily by human-induced emissions of heat-trapping gases. The dramatic effects of climate change include increases in water temperature, reduced frost days, a rise in sea level, and reduced snow cover. As the pace of climate change is expected to […]
